In this abstract, we present an approach for rapid mapping of the whole body B₁ field at 3 Tesla. We use a combination of dual interleaved TR B₁mapping with continuously moving table imaging to measure the B₁ field in the whole body in 90 seconds. Considerable variation is observed in the B₁ distribution in different sections of the body. This measurement will serve as the basis for dynamic B₁ field shimming with the moving table for whole body imaging in future work.
